People can hear my internal sounds (e.g.: Youtube videos, Discord or Slack notification sounds, listening to Voice Messages) through discord and messenger, but not in FaceTime (without using a headphone, and using my built-in MacBook's Microphone).

Hi! As I said above, people can hear my internal sounds (e.g.: Youtube videos, Discord or Slack notification sounds, listening to Voice Messages) through discord and messenger, but not in FaceTime (without using a headphone, and using my built-in MacBook's Microphone).

I have a brand-new only 1 week old MacBook Pro M1 Pro 16 inch version, and this has been going since day 1. I'm using Ventura 13.4.1.

The only things that I managed to observe is that while using Discord, every sound of mine can be heard. e.g: clicking, Youtube, Slack notifications, sometimes typing on keyboard, so almost everything.

while using Facebook's Messenger, only iMusic can be heard in the same way.

And if I'm using FaceTime, then none of these above can be heard. It works perfectly in that way.

If I'm using an external headphone with microphone on it, then it works also perfectly in every app. Nothing can be heard.

It is a bit frustrating, as I don't like using headphones, as they hurt my ears many times.

If you can have any solution, or anyone has had this issue before can give me some tips and tricks, I would be really thankful.

Thank you in advance
